223 Ammo

Introduced in 1964 by Remington Arms, the .223 Remington cartridge was based off of the .222 Remington and the .222 Remington Magnum rounds. Because the .223 Remington round is a light, accurate round as well as being relatively inexpensive and passes the "Walmart Test", it became an instant hit. The 5.56x45mm NATO round was introduced in 1963 and developed by Eugene Stoner. The 5.56mm round is the standard round for NATO forces. You can read more about the cartridge on the 223 ammo wiki.
